Root growth during K+ or Ca2+ stress. cngc11-1, cngc12-1, S90, and their respective wild-type seeds were grown on 0.5× MS agar medium for 7 d before being transferred to 0.5× MS agar medium with various concentrations of Ca2+or K+. Root lengths were measured 7 d after transferring the seedlings to plates with elevated levels of K+ or Ca2+. Data represent the mean of three replicate plates (n=8) ± SE. Asterisks indicate statistically significant differences (Student's t-test, P <0.05). All experiments were repeated at least twice with similar results. (A and B) cngc11-1, open square; cngc12-1, grey triangle; wild type (Col), filled diamond. (C and D), S90, grey square; wild type (Ws), filled diamond.
